To all whom it may concern:

Be it known thatwe, HERBERT E. MARKS and EDWARD C. ROBERTS, both residents of Wheeling, in the county of'Ohio and State of Test Virginia, have invented a new and useful Improvement in` Stud or Partition Construction, of which'the following is a specification.

This invention relates to metallic studs for fire proof buildings and like structures.

The object of the invention is to provide a metallic stud which requires no rivets or other separate fastening. means in the assembling and erection thereof, which is of lattice construction so that pipes and wires can be freely extended therethrough, which is of light weight and cheap to manufacture, which is providedwith means for the attaching `of the lathing thereto, and particularly one which permits the fplaster to key behind the lathing at the points where the studs are located.

The invention comprises the construction and arrangement of parts hereinafter described and claimed.

In the accompanying drawing Figure 1 is a perspective view of a stud embodying the invention and showing the manner of attaching the lathing thereto; Fig. 2 'is a per# spective view of one ofthe vertical angle members of said stud; and Fig. Sis a similar view of one of the cross connecting or lattice members.

The stud is composed of two vertical members l, and a suitable number of cross vconnecting or lat-tice members 2. The -vertical members are preferablyv of angle shape in cross section, as shown, although they may be of other flanged shape, and may be either small rolled angle bars or formed from strips of sheet or thin plate steel bent into angle form. The latter construction is preferred, since light gage metal can be used so as `to save in stock and cost. These angle bars are so placed that the legs or flanges 3 which lie transversely of the partition eX- tendoutwardly or away from each other. The legs or flanges 3 are provided with vertical slots 4. The cross connecting or lattice members 2 preferably are formed from strips of ysheet or thin plate metal, such as steel. The ends of these members are slit longitudinally.. to .provide a plurality Aof tongues 5. Preferably three tongues are provided, huttwo will answer the purpose.

One of the tongues, preferably the middle one when three tongues are provided, is bent' at right angles to. the strip, and extends through a slot 4 in the vertical angle bar, being secured in place by bending the endon the reverse side of'said flange orleg, as shown at 6. This provides a simple and easy manner of connecting the vertical angle bars and securing them so that they can neither spread nor move toward each other.` This is accomplished without the use of rivets or fastening means which are separate from the main members of the stud. The remaining tongue or tongues of the lattice or cross connecting members are permitted to project straight outwardly, and they are of such length as to extend somewhat beyond the edges of the transversely disposed flanges or legs 3 of the vertical angle .of the lathing and then bending or clenching them sidewise.- A single outwardly projecting tongue will suflice, but a plurality of straight outwardly projecting tongues provide a better and more convenient securing means for the lathing, and also, one of them is certain to be in position to project through a mesh of the lathing, and if both are in such position it forms a morel secure fastening for the lat-hing.

The stud can be secured at the oor'and ceiling by any suitable means, the drawings showing one of the legs of the angle bent outwardly ata right angle asl at 9, and the other le'gbent inwardly at a right angle as at 9a, and'e'ach provided with a hole lllfor receiving a spike when the stud is' to be att-ached to Wooden floor or ceiling members, or a rivet, bolt, or similar means wheix the stud is to be secured to metal Hoor or oeiling members.

present a comparatively broad surface against the inner face of the lathing at this point. Heretofere metallic studs have usually been Vso placed that a broad liange or bers 2. These can be quickly and cheaply fabricated by ordinary punching and bending apparatus, and be assembled at either the factory or the place of erection by unskilled labor and by the use of very simple tools. The lathing can be any form of metal lathing and this can be secured to the studs without the use of any special tool. rlfhere are no separate fastening means required either for assembling the parts of the stud or for the attachment of the lathing to the stud. The stud is of open lattice construction. so that wires and pipe can be readily run in all directions. l/Vhile strong, it is light, so that there is a mate- /rial reduction in -stock or tonnage from land provided with slots, and transverse connecting or lattice members having their ends lying against the faces of said outwardly projecting flanges and provided with tongues bent at right angles and projecting through said slots and with other tongues projecting outwardly beyond the edges of said flanges.

2. A metallic stud comprising two vertical angle bars placed with the flanges which lie transversely of the partition projecting outwardly and away from each other and `set our hands.

provided with vertical slots, and flat lattice or connecting members having their ends lying against the faces of said outwardly projecting flanges and slit inwardly from their ends to provide a plurality of tongues, one of said tongues extending through one of said slots and another of said tongues projecting outwardly beyond the edges of said flanges and serving to secure the lathlng. l

3. A metallic stud comprising two flanged vert-ical members having flanges lying transversely of the wall and `provided with'vertiwhich lie transversely of the partition'pro-- jecting outwardly or away from each other and provided with vertical slots, and flat transverse connecting or lattice members arranged flatwise in a vertical plane with` their ends lying against the faces of the outwardly projecting flanges of the vertical members, and being provided with end longitudinal extending tongues 'which are bent at right angles and project through the slots in the vertical members and are bent against the `opposite faces of the latter.

In testimony whereof, we have hereunto HERBERT E. MARKS.
